GAS-ENGINE.

SEDECIFICAION forming part of Letters Patent No. 332,315, dated December 15, 18225.

Application filed September' 17, 1885. Serial No.177,357.

To all whom, 7175 may concern:

Be it known that I, STEPHEN WILcoX, of Brooklyn, in the county of Kings and State of New York, have vmade certain new and useful Improvements in Gas-Engines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which- Figure l represents an elevation, partly in section; Fig. 2, a similar transverse view of the cylinder and connected operative parts of a gas-engine in which my improvements are embodied. Fig. 3 is a sectional view of the igniting device; and Fig. 4, a view of the ignitingwick detached and partly separated to show its structure.

This invention consists of an improved organization, construction, and relative arrangement of the parts, to which I will presently refer in detail, setting forth the advantages, and pointing out thenovel characteristics of the same in the appended claims.

In the drawings, A is the cylinder, B the working-piston, a a the inductioirvalves, and b b the exhaust-valves. In the present in stance these valves are represented aspuppetvalves operated through lifting-toes, a rockshaft, and connecting-rods, in the ordinary way.

C C are two separate combustion-chambers, located at the opposite ends of the cylinder over its respective induction-ports el d, and Within such combustion-chambers the induction-valves a a are placed and operated, the valve-rods passing through the bonnet g, in which a stuffing-box, h, is provided. These combustion-chambers are duplicates, and it will only be necessary to refer to the details vof one for the purpose of this application.

i is a removable shell, provided with an inwardly-projecting flange, k, and a lining, m, and between thelinin g and shell an oilpassage, a, is made, communicating with the oil-supply pipe and with the furnace through the perforations p, as shown.

Theairsupply connection is shown at s,with branch pipes, Fig. 2, leading to the respective chambers C. The air enters the furnace through the opening within the annular flange lo, the latter being more particularly designed for the protection of the bonnet g from the radiated heat of the furnace.

(No model.)

The lighter D (shown enlarged and detached in Fig. 3) is composed of a candle or annular wick, e, placed upon a central tube, j, forming a passage for the air that supports the fiame, and is saturated with oil through the passage Z. The wick e is made up of one or more separate layers of mineral and vegetable fiber, as shown in Fig. 4. The lighter D is located adjacent to and communicates with the furnace of the combustion-chamber, and is provided with an igniting-port, r. Safety-valves WV V are placed at the opposite ends of the cylinder and seated upon the inner walls of the cylinder-head. This arrangement avoids lost space in the cylinder and provides eXterior space for containing the valve-fixtures.

x a; are coverings or protecting-plates, generally made of cast-iron and applied to the surfaces exposed to the heated gas. These plates are recessed on their inner faces, or recesses are made on the adjacent surfaces and filled with a non-conducting material, as indicated in the drawings.

The advantages attending the novel features hereinafter claimed may be summarized as follows:

First. The separate combustion-chambers contain but a fraction of the volume of the combustible, and the division admits of such a reduction in size as to effect a comparative reduction in loss of heat.

Second. In feeding the oil through a passage made between the furnace-lining and its shell, the temperature of the lining is in a degree reduced and the oil evaporated before reaching the furnace.

Third. In providing an inwardly-projecting flange above the furnace, as shown, the bonnet and stuffing-box are protected from the radiated heat of the furnace, also the entering air is materially heated thereby.

Fourth. The location of the safety-valve avoids lost space in the cylinder, and also provides room for the valve-fixtures that would otherwise project beyond the cylinder-head.

Fifth. The metallic coverings having inner recesses for holding the non-conducting material prevent the latter from getting into the cylinder.

Having thus referred to such parts to which my improvements are applied, so that others may understand the same, I do not deem it ILO 3. In a gas-engine, a combustion-chamber constructed with an inwardly projecting ange or annular ring arranged above the point of combustion and intermediate of the sanne and the entering air, for the purposes set forth.

4. A gas-engine having its interior surfaces exposed to the action of the heated gas covered with metallic plates, said plates or adjacent parts having a recessed inner surface filled with a non-conducting material.

l-TEPHEN WILOOX.
